Title: Improvements in or relating to apparatus for the heat-treatment of synthetic fibers
IPC: D02G1/02
Filed: 1957-11-26
Abstract: 870,194. Heating synthetic fibres by electric resistances. MULLER, G. W. Nov. 26, 1957 [Nov. 27, 1956], No. 36855/57. Class 39(3). [Also in Group IX] Apparatus for the heat treatment of moving synthetic fibres with a base of thermoplastic materials comprises several heating elements each with independent means to modify part only of the thermal output of the element so that all the fibres passing through the elements can be heat-treated to the same temperature. Each heater comprises a main resistance wire preferably wound on a former and in circuit therewith an adjustable regulating auxiliary wire resistor preferably wound on a former both adjacent a tube through which the synthetic fibre passes. Thus in Figs. 2 and 3, a metal heat storage block 20 is formed with three passages, the central one containing a replaceable tube 17 through which the synthetic filament passes and the lower one containing a fixed heating resistor 21 supplying 80% of the required heat and connected in parallel with an adjustable resistor 23 wound on an insulating former 23 lying in the upper passage. Brushes 24, 26 are pressed by springs on to the resistor 23, which is adjusted by axial movement of the former 22, which may be rotated by a knob 31 on a threaded rod 30 made rigid with the former and moved axially by the engagement of threads on the knob with threads on an insulating plate 32; or the threaded rod 30 is screwed as shown into the former 22 which is prevented from rotating by a square end 28 held in a square hole in an insulating support 29 so that on rotation of the rod 30, the former is moved axially to adjust the resistor. The end part of the former 22 on which the brush 24 bears is conducting. The block 20 is mounted in glass wool which may be agglomerated by a thermosetting resin in a tin case 16. Alternatively the heating resistor is wound on an insulating sleeve around a metal mass with a central passage housing a central tube for the filament, and the end turns of the heating resistor, which may be more widely spaced or of different resistivity are tapped to regulate the current. The tapped regulating resistor may in a modification be wound on an insulating sleeve extending around the heating resistor, which may be in series with the regulating resistor. The metal mass may be omitted. The tube for the filament may be of metal, glass or a ceramic and may have at each end a nozzle of tempered or nitrated steel of smaller diameter than the tube to reduce heat loss therefrom. The inlet nozzle is flared. In Fig. 5, the tube 47 for the filament is mounted in a metal mass 48 grooved externally to receive eight resistors incorporated in ceramic cylinders. The heating resistors 49, 50 are diametrically opposite and any of the six auxiliary resistors which may be of unequal value are inserted in circuit as required. The resistors are covered by a ceramic envelope 54 and glass wool 52 all enclosed in a metal casing 53.

Title: Improvements in magnetic recording apparatus
IPC: H03K3/12
Filed: 1958-11-19
Abstract: 856,300. Pulse circuits using electric discharge. AMPEX CORPORATION. Nov. 19, 1958 [Nov. 29, 1957], No. 37296/58. Class 40(6). [Also in Group XIX] A magnetic recording head using the non- return-to-zero method of recording digital data comprises a bridge circuit of which one pair of legs form a bi-stable trigger circuit and the other pair is so connected that each leg becomes conducting when the opposite leg of the bi-stable circuit becomes conducting. An input signal 11 is applied to an amplifying valve 13 the anode of which is capacitively coupled to the grid of a valve 16 which is connected to act as a split phase inverter. Thus waveforms 21 and 22 are produced the pulses of which correspond to the leading and trailing edges of input pulses 11 and are of opposite polarity, and are rectified by diodes 26 and 27 before application, rectified waveform 21 to the grid of valve 23, waveform 22 to valve 24. Valves 23, 24 are connected to form an Eccles-Jordan bi-stable trigger circuit which comprises one pair of legs of the bridge circuit. The anode of valve 23 is connected to the cathode of valve 28 through resistances 31, 32, the grid of valve 28 being connected to the common terminal of the resistances. Valve 29 is similarly connected to valve 24 and valves 28, 29 have their cathodes connected through a resistance 36 with which the recording head 39 is connected in parallel. Voltage is applied to the anodes of valves 28, 29. In operation, for the waveform shown, a trigger pulse form waveform 22 is applied to the grid of valve 24 rendering it conductive. Valve 29 does not become conductive since the grid is at less potential than the cathode, however valve 28 is conductive since grid and cathode are at the same potential and anode potential of valve 23 is high. There is thus a low impedance path through valve 28, the recording head 39, the resistances 33, 34, valve 24 and resistance network 37 to ground, resulting in the magnetic medium e.g. tape or disc being saturated in one direction. A trigger pulse applied to valve 23 will set up a low impedance path through valve 29, recording head 39, resistances 31, 32, valve 23 and network 37 to ground resulting in the magnetic medium being saturated in the opposite direction.

Filed: 1946-12-21
Abstract: 622,756. Fluid-actuated valves. BENDIX AVIATION CORPORATION. Dec. 21, 1946, No. 37605. Convention date, Dec. 21, 1945. [Class 135] [Also in Group XXXIV] A relay valve mechanism, for use in the vacuum braking system of a tractor-trailer vehicle combination, has a central spindle 70 connected to three diaphragms 46, 62 and 78. The diaphragm 46 divides a chamber 48 in communication through port 38 with the brake cylinder on the trailer unit, from a chamber 50 open to atmosphere through port 42 and controls interconnected poppet valves 54 and 56. The diaphragm 62 divides a chamber 68 connected through port 40 with a brake control valve on the tractor from chamber 66 connected by passage 74 to port 36 leading to the trailer vacuum reserve tank, the chamber 66 being therefore always under vacuum. Diaphragm 78 divides a chamber 84 connected by passage 86 to chamber 50 and therefore always open to atmosphere from a chamber 82 adapted to be connected by means of solenoid-operated valve 100 alternatively either to control valve port 40 by passage 98 or to chambers 84 and 50 and therefore also to atmosphere by passage 94. The valve mechanism is shown in the brakes released condition with the diaphragm 78 balanced by atmospheric pressure on each side. Initial application of the driver's pedal on the tractor unit energizes solenoid 112, moving valve 100 to the right, thus applying vacuum in chamber 68 and port 40 to chamber 82 so that diaphragm 78 raises spindle 70 and valve 56 and connects vacuum tank connection 36 with brake cylinder port 38, thereby providing an application of the trailer brakes in advance of the tractor brakes before the normal graduated rise in both braking pressures takes place.
